Question

我想在ActivityIndicator上添加UIButton所以我确实喜欢这个

-(IBAction)SetNationality:(id)sender
{

actInd=[[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0, 0, 40, 30)];
[btnpost addSubview:actInd];
[actInd startAnimating];

NSMutableDictionary *dictionaly=[[NSMutableDictionary alloc] init];
[dictionaly setValue:[NSNumber numberWithInt:0] forKey:@"NationalityCode"];
[dictionaly setValue:@"nationalitytest test" forKey:@"NationalityName"];
[dictionaly setValue:[NSNumber numberWithInt:0] forKey:@"Deleted"];
[dictionaly setValue:[NSNumber numberWithInt:1] forKey:@"Status"];

NSMutableDictionary *dictNationality=[[NSMutableDictionary alloc] init];
[dictNationality setObject:dictionaly forKey:@"Nationality"];


 [wb prepareURL:@"ProfileConfig/Nationalities" :@"" :YES :NO :dictNationality:^(NSString *status)
{

    [self DataReceived];



    }];
}

然后我删除此方法中的活动指示器

-(void)DataReceived
 {

  [actInd removeFromSuperview];
  NSLog(@"data array %@",dm.arrayData);
  }

但我的问题是activityindicator没有从超级视图中删除。它不停旋转。我怎么解决这个问题。感谢

试试这段代码：

Answer 2

无需从父视图中删除活动指示符。只需停止活动指示器动画即可。

-(void)DataReceived
{
   dispatch_async(dispatch_get_main_queue(), ^{
       [actInd stopAnimating];
   });
}

希望这可以帮助你：

- (void) hideActivityIndicator {

    actInd.hidden = YES;
    [UIView animateWithDuration:0.3 animations:^{
    actInd.alpha = 0.0;
   }  completion:^(BOOL finished) {
     [actInd stopAnimating];

   }];

}

以编程方式创建的活动指示符未删除
